简要总结
The purpose of this study is to find out whether or not antibodies to the donor bone are present in the blood of patients who receive the donor bone.
详细描述
Patients who have bone cancer often have the cancerous bone removed by surgery and replaced with a piece of bone taken from a donor (a person who donates parts of their body to be used for transplants after their death). However, sometimes this replacement bone does not heal together with the patient's bone. The reason the bone does not heal is not known but it is thought that the patient's body may react to the donor bone by producing antibodies against cells on the donor bone. The purpose of this study is to find out whether or not antibodies to the donor bone are present in the blood of patients who receive the donor bone. You have been asked to participate in this study because you are scheduled to undergo this type of surgery.

入选标准
- •Patients twelve years or older who are scheduled for massive fresh-frozen human structural bone allograft implantation at participating centers will be given the opportunity to participate in the study. All patients must have a reconstruction of the involved long bone with either an intercalary graft, an osteoarticular graft, or an allograft/endoprosthesis composite graft. The junction or union site studied will be the cortical-cortical, host allograft junction site, not the cancellous interfaces.
排除标准
- •Patients who do not require major weight bearing cortical allograft bone grafts will be excluded. Also, women who are or could potentially become pregnant will be excluded from the study.
